Week 18
心得：
很開心能完成屬於自己的機器人，還能讓機器人自動跳舞。也看到很多其他人的作品，有很多令人感到驚奇的，很開心能修到老師的這門課，學習到很多。

Week 14 20170612 鄭雅至的課堂筆記
Week 14
HW 1
背景貼圖。
1. 先下載並安裝 OpenCV2.1 (include + lib + bin)。
*此步驟要注意
2. 下載 myEarth 變背景貼圖。把 display 裡 /// 畫地球
程式碼：
glBegin(GL_POLYGON);
glTexCoord2f(0,0);glVertex3f(-1,+1,0);
glTexCoord2f(1,0);glVertex3f(+1,+1,0);
glTexCoord2f(1,1);glVertex3f(+1,-1,0);
glTexCoord2f(0,1);glVertex3f(-1,-1,0);
glEnd();
HW 2
打開自己的模型套用。背景貼圖+打光。
程式碼：
void display()
{
glEnable(GL_TEXTURE_2D);
glDisable(GL_LIGHTING);
glPushMatrix();
glBegin(GL_POLYGON);
glTexCoord2f(0,0);glVertex3f(-1,+1,0.2);
glTexCoord2f(1,0);glVertex3f(+1,+1,0.2);
glTexCoord2f(1,1);glVertex3f(+1,-1,0.2);
glTexCoord2f(0,1);glVertex3f(-1,-1,0.2);
glEnd();
glPopMatrix();
glDisable(GL_TEXTURE_2D);
glEnable(GL_LIGHTING);
}
int myTexture(char *filename)
{
IplImage * img = cvLoadImage(filename); ///OpenCV讀圖
cvCvtColor(img,img, CV_BGR2RGB); ///OpenCV轉色彩 (需要cv.h)
glEnable(GL_TEXTURE_2D); ///1. 開啟貼圖功能
GLuint id; ///準備一個 unsigned int 整數, 叫 貼圖ID
glGenTextures(1, &id); /// 產生Generate 貼圖ID
glBindTexture(GL_TEXTURE_2D, id); ///綁定bind 貼圖ID
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT); /// 貼圖參數, 超過包裝的範圖T, 就重覆貼圖
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT); /// 貼圖參數, 超過包裝的範圖S, 就重覆貼圖
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST); /// 貼圖參數, 放大時的內插, 用最近點
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); /// 貼圖參數, 縮小時的內插, 用最近點
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, img->width, img->height, 0, GL_RGB, GL_UNSIGNED_BYTE, img->imageData);
return id;
}
void myInit()
{
id = myTexture("image.jpg");
}
int main()
{
myInit(); ///我的 init 初始化 把貼圖準備好 前面OpenCV 2行, 後面 OpenGL 9行
///一定要在glutMainLoop()之前，不可放在最前面
}

Week 13 20170605 鄭雅至的課堂筆記
Week 13
HW 1
利用 Excel 了解內插公式。
 |
HW 2
打開自己的模型。增加內插公式的函式與Timer函式。
函式：
float alpha=0.0;
float oldAngle[9]={0,0,0,0,0,0,0,0,0};
float newAngle[9]={40,40,-40,-40,0,0,0,0,0};
void interpolation()
{
for(int i=0;i<9;i++){
angle[i]=alpha*newAngle[i]+(1-alpha)*oldAngle[i];
}
alpha+=0.1;
}
void timer(int t)
{
glutTimerFunc(1000,timer,t+1);
interpolation();
glutPostRedisplay();

Week 11 20170515 鄭雅至的課堂筆記
Week 11
HW1
1. 今日小考內容(T-R-T)：
glPushMatrix();
glTranslatef(x,y,0); // 再把會旋轉的物體掛在(x,y,0)上
glRotatef(angle,0,0,1); // 對Z軸做旋轉angle角度
glTranslatef(-x,-y,0); // 把旋轉中心點放在畫面中間
物體;
glPopMatrix();
P.S 要由下往上
2. 下載 OpenCV2.1，並且安裝他。
3. 確認 C:\OpenCV2.1 \ include \ opencv \ 很多.h檔
\ lib \ 很多lib檔
\ bin \ 很多dll檔
4. 新增貝殼專案 File -> New -> Project (要用C++)
程式碼：
#include <opencv/highgui.h>
int main()
{
IplImage * img=cvLoadImage("C:/img.png");
cvShowImage("a", img);
cvWaitKey(0);
}
HW2
1. 下載 freeglut 到桌面上。
2. myEarth 專案檔開啟並執行。
(image.jpg，圖 + freeglut.dll + 安裝opencv2.1，可開圖 + 專案cbp + 程式cpp)
程式碼：
#include <opencv/highgui.h> ///for cvLoadImage()
#include <opencv/cv.h> ///for cvCvtColor()
#include <GL/glut.h> ///3D glut
#include <stdio.h>
GLUquadric * quad;
GLuint id;
float angle=0;
void display()
{ glEnable(GL_DEPTH_TEST); ///要啟動 Detph Test 深度值的測試,3D顯示才正確
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glPushMatrix();///自動轉很帥
glRotatef(90, 1,0,0);
glRotatef(angle, 0,0,1);///自動轉很帥
gluQuadricTexture(quad, 1);
gluSphere(quad, 1, 30, 30);
glutSolidTeapot(0.3);
glPopMatrix();///自動轉很帥
glFlush();
}
void timer(int t)
{ glutTimerFunc(20, timer, 0);/// 1000 msec 50fps:20msec
angle+=1;///自動轉很帥
glutPostRedisplay();
}
int myTexture(char *filename)
{
IplImage * img = cvLoadImage(filename); ///OpenCV讀圖
cvCvtColor(img,img, CV_BGR2RGB); ///OpenCV轉色彩 (需要cv.h)
glEnable(GL_TEXTURE_2D); ///1. 開啟貼圖功能
GLuint id; ///準備一個 unsigned int 整數, 叫 貼圖ID
glGenTextures(1, &id); /// 產生Generate 貼圖ID
glBindTexture(GL_TEXTURE_2D, id); ///綁定bind 貼圖ID
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT); /// 貼圖參數, 超過包裝的範圖T, 就重覆貼圖
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT); /// 貼圖參數, 超過包裝的範圖S, 就重覆貼圖
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST); /// 貼圖參數, 放大時的內插, 用最近點
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); /// 貼圖參數, 縮小時的內插, 用最近點
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, img->width, img->height, 0, GL_RGB, GL_UNSIGNED_BYTE, img->imageData);
return id;
}
void myInit()
{ quad = gluNewQuadric();
id = myTexture("image.jpg");
}
int main(int argc, char**argv)
{ glutInit(&argc, argv);
glutCreateWindow("3D");
glutDisplayFunc(display); ///顯示
glutTimerFunc(0, timer, 0);
myInit(); ///我的 init 初始化 把貼圖準備好 前面OpenCV 2行, 後面 OpenGL 9行
glutMainLoop();
}
